Biking is an amazing family activity，but finding a route that is suitable for different，ages is a little difficult．Lee McNeil and his family ate crazy about biking．They have seven children，from 4 to 24 years old．When looking for a route，they look for enough protection from traffic，good surface condition and interesting views．

Here are some great routes for biking with your whole family which are suggested by McNeil．

Iron Horse Trail

This is the McNeil family's favorite ride．The route ~s 26 miles and goes through the 2．1 mile Snoqualmie Tunnel．"Beautiful views，the tunnel，and places to stop and watch the rock climbers make it special，" McNeil said．"All our kids have taken their turn to go through the black tunnel bravely for the first time and we celebrate it at the end of the ride．" If you prefer，check http://bit，ly/Mlt9y4 for more information．

Centennial Trail

The Centennial Trail runs for 23 miles from Snohomish to Bryant．The trail is wide and smooth，and is safe for kids as it is off the roads．A nice stop is Lake Cassidy east of Marysville．A dock（码头） on the lake is fun to explore．It also has picnic tables and washrooms for a convenient（方便的） lunch-time stop．For a map，go to http：//bit．ly/L5qCeY．

Cascade Trail

The Cascade Trail is 23 miles．The slope（斜坡） is gentle and it makes for an easy family ride．McNeil said it is a "beautiful ride up the Skagit Valley，with lots of places to watch wildlife along the river"．Go to http://bit，ly/PR4wOW to see a map showing the trail，parking areas and bus stops．

Cause and effect is one way to explain things that happen around us. Many things happen because something caused or influenced them to happen. Sometimes it is hard to look at a cause and find out what causes the effect. It may help you to start with the effect and use your reasoning (推理的) skills. Think about all the things you know that could be reasons for the effect you can see.

For example，you may see someone putting on a heavy jacket. This is the effect. To look for a cause, think to yourself, “What would make someone put on a heavy jacket?” Maybe the person is going outside into very cold weather. Maybe the person works in the penguin pen (企鹅圈养地) at Sea World. Maybe the person is going to visit an ice skating rink where the air is kept very cold. All of these things could be a cause for putting on a heavy jacket.

Now, think about a second example. The effect is a boy named Tony has to go to the head teacher’s office. What are the possible causes? Maybe he fought with another student. Maybe he is just being picked up early. Maybe he is being given a prize!

Here is another example for you to think about its cause and effect. Carol，13，was trying to fall asleep when her 8-year-old brother, Doug, came into her room. He looked around a bit，but seemed really out of it. Then Doug went back into the hallway and stood there looking straight up at the hall light for quite a while. Little brothers can be very strange，but this was really much too strange. Carol didn’t know what to do. Just then, Carol’s father appeared and explained that Doug was sleepwalking. What’s the cause and effect, could you tell?

1.According to the second paragraph，which of the following is an effect?

A. Someone puts on a heavy jacket.

B. Someone works in the penguin pen.

C. Someone will go outside into cold weather.

D. Someone will go to visit an ice skating rink.

2.Tony has to go to the head teacher’s office. Which of the following isn’t the possible cause?

A. He fought with another student. B. He is going shopping.

C. He is being picked up early. D. He is being given a prize.

3.What was Doug doing when his sister Carol tried to fall asleep?

A. He was going outside. B. He was reading a story.

C. He was sleepwalking. D. He was looking for his dad.

A. Tony got up and had a glass of water.

B. We came home and found him sleeping.

C. The ball was lost and a window was broken.
